Assessing UST Corrective Action Technology: A Scientific Evaluation of theMobility of Organic Contaminants in Subsurface Environments

摘要

The problems associated with leakage of motor fuels and organic chemicals fromunderground storage tanks (USTs) are compounded by a general lack of understanding of the partitioning, retention, transformation, and transport of these contaminants in the subsurface environment. The research material presented herein is the result of an intensive data collection and evaluation. The objective of the research was to compile the most up to date and comprehensive knowledge of contaminant behavior in the subsurface into a single document. It provides an understanding of microscale fate and transport processes as a means to understanding the larger scale movement of contaminants. This, in turn, leads to a more thorough understanding of the application of corrective measures and remediation techniques. The microscale analysis focuses on 13 loci, each of which represents a location and condition in the subsurface environment where and how contaminants may exist after an UST release.
